Forms

κᾰτηγορῐ́ᾱ (katēgoríā) f (genitive κᾰτηγορῐ́ᾱς); first declension[1]

Etymology

It is from Ancient Greek κατηγορέω (katēgoréō, “to accuse; to assert”), with the suffix -ία (-ía).[1][2] The verb is from κατήγορος (katḗgoros, “accuser”), or directly from κατά (katá, “against”) and ἀγορεύω (agoreúō, “to speak in the assembly”),[1] a verb from ἀγορά (agorá, “assembly”).[2]

Earliest recorded meaning

It is first found in the 5th century BC, in Herodotus and Thucydides, meaning an accusation, and Thucydides sets it against a mere complaint, αἰτία (aitía).[3][4]

Semantic evolution

In the Attic orators it was the prosecution in court, and Aristotle's Rhetoric sets it against the defence, ἀπολογία (apología).[5][3] Later prose also used it for criticism in general.[5]

Aristotle turned the word into a term of logic: by his time the verb's sense “accuse” had weakened to “assert, name”,[2] and κατηγορία became the act of predicating something of a subject, then the predicate itself, and above all one of the highest classes of predicates, the categories, which he counts as ten in the Topics but as eight or seven elsewhere.[3][5]

In the New Testament it is again an accusation brought against someone (John 18:29; 1 Timothy 5:19), and it passed as a loanword into rabbinic Hebrew.[6] Medieval vernacular Greek, with the by-form κατηγοριά (katigoriá), used it for blame and also for testimony.[7] The logical term went into Late Latin as Latin categoria and, through French catégorie, into English category in the 1580s.[2] Modern Greek κατηγορία (katigoría) continues the ancient word as “accusation”; its everyday sense “category, class” is a semantic loan from French.[8]
